On the curved wall below the vaults Pietro created the huge Crucifixion, the most ambitious of all pre-Renaissance crowd scenes; it comprises some fifty figures, each strongly differentiated. Under the Crucifixion, at eye level, he painted a 'sacred conversation', Mary and Child between Sts Francis and John the Evangelist.
